Microsoft's blockchain

1. Go is an open source programming language, which makes it easy to construct simple, reliable and efficient software. If you want to learn this programming language, you should first find a good tutorial. Brother Lian's go language + blockchain training has recently published a new set of go language tutorial, and the teacher's speaking is very good

with the global hot discussion of the concept of "blockchain", the application of blockchain technology has been quietly added to the daily life scenes such as finance, logistics, credit reference, manufacturing and retail. Some experts have shown that the future blockchain will be closely related to people's lives, and the integration of blockchain technology and people's daily life is the general trend

the popularity of the blockchain market has triggered a large number of talents demand based on blockchain technical personnel, and the popularity of blockchain talents is rising at the speed of light. According to the "2018 blockchain high salary list" released by lagou.com, Tencent, Xiaomi, Suning, Jingdong and other domestic enterprise giants have released many high salary blockchain post demands, trying to explore blockchain related technologies and applications. It is also pointed out in the list that the demand for high salary jobs is mainly based on blockchain related technical jobs, among which Suning and Keda have been given the highest monthly salary of 100k

the huge market demand for technical talents will inevitably lead to the explosive emergence and growth of the whole blockchain training market. Most of the training modes can be divided into online training, traditional IT organization training, and offline short-term training camps, which mainly focus on high-end forms. However, in the process of the hot market evolution, there are also a variety of blockchain training chaos: lecturers' qualifications are watered down, and even the most basic names are not disclosed, the syllabus is opaque, and the teaching quality is shrinking, Unreasonable class arrangement and uneven training fees and so on

with the large-scale development of the whole blockchain training market, brother company ecation, together with Yin Cheng, a senior blockchain expert, and his Tsinghua Shuimu Weiming team, has set up a blockchain college. With its professional and powerful team of technical lecturers, detailed and comprehensive curriculum system, and a large number of authentic enterprise blockchain projects, it aims to deepen the blockchain teaching and training field, And train more professional technical talents for enterprises and society<

Yin Cheng, a senior blockchain technology expert, graated from Tsinghua University, is the dean of brother Lian blockchain college. He once served as Google Algorithm Engineer, the world's most valuable expert in the field of Microsoft blockchain, and the gold medal lecturer of Microsoft tech.ed conference. Proficient in C / C + +, python, go language, sicikit learn and tensorflow. With 15 years of programming experience and 5 years of teaching experience, senior software architect, Intel Software Technology expert, famous technology expert, with many years of working experience in the world's top it company Microsoft Google. He has many years of experience in software programming and lecturing, and has developed many procts in human-computer interaction, ecation, information security, advertising and blockchain system. He has deep experience in project management and R & D, has two AI invention patents, and has practical experience in developing e-money deployed to Microsoft Windows azure. Teaching explanation is in simple language, so that students can apply what they have learned

Sharing area network:

the application scope of blockchain technology is still very wide. Based on the characteristics of decentralization, distrust, collective maintenance and reliable database, its application in the financial instry is the first step
blockchain is the underlying technology of bitcoin, and the application and development of blockchain in digital currency is mature

like the block chain based trading system development scheme provided by Yingtang Zhongchuang, the developed software system has great safety factor and transparency

3. In many cases of blockchain application, we can always see the word baas. Baas is the abbreviation of blockchain as a service, which is translated into "blockchain as a service" in Chinese. So what is blockchain as a service baas? With this question, we will follow Xiao Wang of Renren blockchain technology team to discuss it carefully
according to Xiao Wang, the concept of blockchain as a service (baas) is mainly proposed by Microsoft and IBM. To put it bluntly, it is actually a new type of cloud service, a cloud service combined with blockchain technology. For example, Microsoft's azure cloud computing platform and IBM's bluemix garage cloud platform all provide blockchain as a service baas
blockchain as a service (baas) is a space created by enterprises such as Microsoft and IBM from their own cloud service network to run a blockchain node. Compared with ordinary nodes and exchange nodes, the main purpose of baas nodes is to quickly establish the development environment they need, and provide a series of operation services based on blockchain, such as search query, transaction submission, data analysis, etc. these services can be centralized or decentralized to help developers verify their concepts and models faster. The service of baas node is reflected in: stronger tool, easy to create, deploy, run and monitor blockchain..

This is two different concepts. According to different standards, blockchain can be classified into three categories:

& # 8195&# 8195; 1) According to the network scope of blockchain, it can be divided into public chain, private chain and alliance chain

 &# 8195; 2) According to the docking type of blockchain, it is divided into single chain, side chain and interconnection chain

 &# 8195; 3) According to the display environment of blockchain deployment, it can be divided into main chain and test chain

the main chain can be understood as a formal online and independent blockchain network, while the public chain refers to a blockchain that can be read by anyone, can send transactions and can be effectively confirmed by anyone, and can participate in its consensus process

5. Blockchain is an important concept of bitcoin. In essence, it is a decentralized database and the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
blockchain is public on the network and can be queried in every offline bitcoin wallet data. The function of bitcoin wallet depends on the confirmation with the blockchain. An effective inspection is called a confirmation. Usually, a transaction needs to obtain several confirmations. The lightweight bitcoin wallet uses online confirmation, that is, it will not download the blockchain data to the device storage
many of bitcoin's competitors also use the same design, but the workload proof and algorithm are slightly different. For example, the use of proof of interest and scrypt and so on<

the concept of blockchain time stamp certificate service and proof of existence was proposed in the white paper [1] of Nakamoto Tsung, which created the first block, namely "Genesis block"< On January 3, 2009, the founder of bitcoin, Mr. Nakamoto, left an unchangeable sentence in the genesis block:
"the times 03 / Jan / 2009 Chancellor on brink of second low for banks (on January 3, 2009, the chancellor of the exchequer was on the verge of implementing the second round of bank emergency assistance)."
at that time, the British Chancellor of the exchequer, darling, was forced to consider a second attempt to relieve the banking crisis, which was the headline of the front page article of the times that day
the time stamp service and existence proof of blockchain, the time generated by the first blockchain and the events that happened at that time are permanently preserved
BTCC, a bitcoin company, launched a service "Millennium chain" in 2015, namely blockchain lettering service, which is based on the above principles. Users can use this service to engrave text on the blockchain and save it permanently
bitcoin, Laite coin, Ruitai coin and Qianjin card are all digital currencies based on blockchain technology.

7. Today's Internet, has almost perfectly solved the problem of information transmission, anyone, at any time, anywhere can carry out simple and fast information transmission at low cost; However, the transmission of value still depends on the central organization accounting, and the end-to-end direct transmission of value is still not realized. Blockchain technology, as a trust building machine, establishes trust through algorithms, and accounts by the network rather than the central organization, realizing the end-to-end transfer of value. In short, blockchain is a distributed shared accounting technology. It is a database that can not tamper with the time ordered cryptography account book, which is jointly maintained by multiple nodes and guaranteed by a unified consensus mechanism. As the first technology that can establish decentralized trust from the technical level, blockchain has subversive significance. On the blockchain, anyone who doesn't know each other can complete end-to-end bookkeeping, data transmission, authentication or contract execution by virtue of the open and transparent trust relationship of database endorsement, without reaching a credit consensus through an intermediary in advance< br />?
Bubi (Beijing) Network Technology Co., Ltd. (hereinafter referred to as Bubi) is a leading blockchain technology service provider in China. Since its establishment, Bubi has been focusing on the R & D and innovation of blockchain technology and procts. It has a number of core technologies, and has made substantial innovation in many aspects, forming a number of core technological achievements, For example: mathematically proven distributed consensus technology, fast large-scale account book access technology, multi chain general ledger technology supporting business form expansion, interconnection technology between heterogeneous blockchains, etc. We have developed our own blockchain basic service platform, which has been applied in equity, supply chain, credit and other fields. Bubi has been committed to building an open value circulation network with the core of decentralized (polycentric) trust, so that digital assets can flow freely
on April 25, China's first asset based blockchain integration platform, gege integration, jointly built by Bubi company and Guangdong gege Integration Application System Co., Ltd., was ceremoniously launched“ "Gege integral" introces the integral system into the concept of blockchain. It is jointly opened by multiple parties, and points are issued and exchanged to promote the circulation of points. All cooperative institutions can jointly participate in transaction verification, account book storage and real-time settlement; The third-party payment platform of the enterprise points issuer makes the points in and out more flexible
traditional points are debt based points, which are characterized by scattered points, weak consumption, more restrictions on use, cumbersome exchange and difficult circulation. If a merchant "issues" the integral, B merchant does not give cash; At the same time, the points can not be transferred or given away, which leads to the limited brand communication of the points issuers. In addition, the use of traditional points often has a certain period of time, which will be automatically cleared after expiration. The grid points with blockchain as the bottom layer have the following characteristics: the number of points issued by each merchant can not be forged, tampered or deleted; Lattice integral has a unique number, and the circulation of all integral can be traced; The integral data is stored in the whole network, even if 99% of the network fails, the integral information will not be lost. The validity period of grid points is permanent by default, and users can hold and use it with confidence. This kind of integral has the characteristics of free circulation, mutual gift, convenient exchange, breaking into a whole, comfortable communication, etc. for users, it is more disposable and more valuable. For merchants, the active points promote brand communication, increase the stickiness of consumers and merchants, and also benefit merchants to share and complement customer data
at the press conference, a number of contractors issued bonus points. The guests experienced the whole process of points collection, gift and exchange. Nearly a thousand participants also experienced points collection, account creation and points transfer. This unprecedented barrier free exchange of points made the interactive atmosphere of the conference high
Huang Xiaogang, chairman of Guangdong gege integral operation system Co., Ltd., said that the gege integral platform will be a super large integral platform. With the rapid growth of users, the number of businesses entering will increase and the brand effect will become greater and greater. As an open business integral platform, it will bring a revolutionary reform to China's integral system. Bubi firmly believes that there will be more and more store points merchants accessing the platform to jointly build a trusted digital asset platform and realize the free distribution and circulation of points. Then, Bubi team will also give more support in the field of blockchain technology. The Internet in the future must be an infrastructure that can provide reliable and free flow of value

Jiang Hai, founder of Bubi blockchain: let digital assets flow

Dr. Jiang Hai has a deep accumulation in blockchain technology, distributed computer network and network information security. Bubi company, founded by him, focuses on the innovation of blockchain technology and procts, has a number of core technologies, and has developed its own blockchain service platform. With decentralized trust as the core, we are committed to building an open value circulation network to let digital assets flow freely

Yu Tingting: please introce Dr. Bu Jiang to us what Bubi does<

Jiang Hai: what Bubi needs to do is a new technology and proct to realize the real value circulation and make the Internet reach a new height. With the application of this technology, when transferring assets, there will be no central organization, which can realize the direct transfer of assets between us. In the future, if the network itself can settle the bill, we can transfer it directly, and we don't need to go through an intermediary< Guo Feng: with the development of Internet in China for more than 20 years, the zero cost transmission of point-to-point information has been solved, but the transmission of value and credit is difficult to achieve. Is there a way to solve this problem? Fortunately, there are! That's what Bubby is doing<

Yu Tingting: it sounds like a world shaking thing to me. Even you will eliminate many instries and remove the intermediary of many instries<

Jiang Hai: at present, all the major banks, investment banks and exchanges are carrying out initial research and experiments in this field

"blockchain" is the underlying technology of bitcoin, like a database ledger, recording all transaction records. Because of its safety and convenience, this technology has graally attracted the attention of the banking and financial instry

Jiang Hai: because today's blockchain technology, which has attracted worldwide attention, is completely different from the original bitcoin blockchain technology

Yu Tingting: so you (Guo Feng) are investing in the brains of these scientists< Guo Feng: traditional technology plus blockchain can make the technology to a new level. In fact, what they are doing now is blockchain +

Yu Tingting: now, from the perspective of an investor, is there any risk<

Guo Feng: if the real disruptive innovation is too tangled with its business model at the beginning, it will not be invested. The greater the differentiation, the greater the prospect of the business model. This is my understanding. However, there is no company in China to do the underlying technology, so we did not hesitate to invest in such a team<

Jiang Hai: I hope our common cause will blossom and bear fruit in 2016 and after 2017, and we can go to the international forefront in the blockchain instry

Yu Tingting: I hope I have the honor to witness it.

8. At present, blockchain technology is mainly applied in smart contract, identity authentication and asset transaction

in addition to solving the security problem, blockchain technology can also change the following areas:

1. In the future, music right distribution is likely to enter the stage of blockchain, removing the intermediate link, so that musicians can get more direct income. In the past, record companies or the Internet were required to increase user stickiness. There were a lot of fees in the middle of promotion or song playing, but not many were really given to the authors, because the original right was still in the hands of several major record companies

2. Writing right is the same. For example, you may have to find a publisher before. This right can't be sold many times, and the money given to the author is also very small. With blockchain technology, all users need to pay the right fee to the author, not limited to a single publisher. Previously, Mr. Li Xiaolai did the press one project, which is mainly aimed at right distribution

3. The Internet of things and blockchain technology will combine to proce the blockchain Internet of things (Biot). Blockchain Internet of things can greatly rece the risk of hacker attacks. With the help of blockchain Internet of things, it may be as convenient as mobile phones to obtain warehouse sensor data

Kevin Kelly's book out of control has become the wind vane of the development of the Internet. In his later book necessity, he also mentioned that "technology has a preference in nature, which makes it move in a certain direction. On the premise that other conditions are the same, the physical and mathematical principles that determine the development of science and technology will favor certain specific behaviors

the development of blockchain technology is an "inevitable" trend, and bitcoin and some valuable digital currencies are only proced because of one of the needs. Today's blockchain is like the Internet in 1994. The development of the times will screen out the best technology and procts. It's just a matter of time

now there are too many "pseudo blockchain" projects focusing on blockchain, because too many people blindly invest in them without understanding. I want to make a fortune in this market. Those people are aiming at leeks that enter the coin circle without learning anything. They casually make small packages on the open public chain, issue a coin, hold a roadshow and want to circle a group of people to come in. They want to run after they circle money. In fact, they have no actual technical content and can't solve any practical problems.
